Sand mastic in Jealott's Hill
Across Jealott's Hill, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on brick reveals, period & listed homes and timber door frames, and the jobs we see most are patchy fillers round a sash window and draughty sash windows at the surround.
Somewhere as small as Jealott's Hill, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Jealott's Hill and everywhere else we cover.

Why it’s worth doing now in Jealott's Hill
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Jealott's Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Common problems we fix in Jealott's Hill
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice one of these:
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
Homes close to Church of St Michael and All Angels include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Who does the work, and how experienced they are
- Whether you can choose the colour
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
Honest limits
A few problems are outside what sealant work can do:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
- Sashes that rattle, stick or won’t open
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Timber door frames
- Brick reveals
- Period & listed homes
- Tenement windows
- Sash and case windows
- Stone surrounds
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
- Don’t paint over the new mastic
- Find out about consent before window work on a listed home
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Jealott's Hill: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as St Leonard's Hill (about 4.5 miles east) nearby, there’s older building stock in the area around Jealott's Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Garth Hill College, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Bracknell station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
